Or at least CPU / Memory / motherboard / OS dependant. If you have two machines with identical configurations, you would most likely get similar values.

Default backend and thread backends?
by Alexander Demenshin 05 Feb '04

05 Feb '04

Hi, Is there any way to _change_ default backend? Something like Pike.DefaultBackend->replace(MyBackend) - so all subsequent calls to call_out() and all file descriptors allocated after this will use new backend? And more... It would be nice to have dedicated backends in some threads, so (say) all calls to call_out() and fd's allocation will use thread-specific backend (if it is set - and default otherwise). Something like Thread.Thread()->set_backend()... All this … [View More]

sscanf format parameter for whitespace
by Peter Lundqvist (disjunkt) ＠ Pike (-) developers forum 05 Feb '04

05 Feb '04

Just a thought. It would be darn sexy with a format parameter for whitespaces in sscanf (for whitespace elimination)? array_sscanf(" void foo(10)", "%*w%s%*w%s(%d)" ); array_sscanf(" void foo(10)", "%*[ \t]%s%*[ \t]%s(%d)");

Object comparision in C module
by Alexander Demenshin 05 Feb '04

05 Feb '04

Hi, How to compare two objects which are implemented in C module? What I don't know is how to make sure that other object is of same type. Is it field "subtype", or? Where object type is stored and how it is assigned, BTW? Thanks! Regards, /Al

Crypto naming
by Niels M�ller (v�ssar r�dpennan) ＠ Pike (-) developers forum 04 Feb '04

04 Feb '04

I've browsning some of the code, and have a few comments. I think Crypto.SHA ought to be renamed Crypto.SHA1. The name Crypto.Proxy is somewhat strange (it's actually a buffer). Perhaps it should be renamed, and perhaps it would make sense with a feed/drain interface. Also the pad method looks a little strange, PIKEFUN string pad() { ptrdiff_t i; for (i = THIS->backlog_len; i < THIS->block_size - 1; i++) THIS->backlog[i] = DO_NOT_WARN((unsigned char)(my_rand() &… [View More]

mktime
by Marcus Comstedt (ACROSS) (Hail Ilpalazzo!) ＠ Pike (-) developers forum 03 Feb '04

03 Feb '04

The function my_tm_diff() in buildint_functions.c is bugged. It doesn't differentiate between months of different length, but treats all months as having 30 days, 10 hours and 30 minutes. This means that e.g. the dates 2004-01-31-12:00:00 and 2004-02-01-01:30:00 will be considered _equal_. The recent failures of the testsuite is due to these state of affairs. The bug can be reproduced with mktime(gmtime(1075550400)) The bug is likely to occur with any date being the last day of a month … [View More]

Pike module initialization at compile time
by Alexander Demenshin 03 Feb '04

03 Feb '04

Hi, I asked this once on general Pike list, nobody answered, so I'll try here :) The question is - why create() is called when module is inherited, not when it is instaniated? If there is Parent.pmod (with create() defined), and Child.pmod, which inherits Parent, then create() defined in Parent will be called when Child is _compiled_. Compilation of Parent won't call it's create() method. In case if module is _imported_, such behavior is logical, but when inherited... What … [View More]

Re: Default backend and thread backends?
by Martin Stjernholm, Roxen IS ＠ Pike developers forum 02 Feb '04

Correction: Thread A might release its read lock after checking that the object is thread local, and then the fact that no other thread can access it is relevant. I don't think it'd be good to make threads keen on releasing the read lock though, since they can't reasonably do any significant amount of work without reading global objects.
